Description

Technical Field

[0001] The utility model relates to the technical field of water-ink printing, in particular to an oven used for a water-ink printing machine. Background Art

[0002] Ink printing has been gradually phased out due to its high levels of volatile organic compounds (VOCs) and harmful ingredients. It has been replaced by water-based printing, a method that uses water as a solvent and ink as a pigment, applied to materials such as paper, cloth, and plastic using a printing press. Because it contains no VOCs, it significantly reduces VOC emissions, alleviating air pollution and health risks to operators. It is environmentally friendly, offers high definition, and vibrant colors, and is widely used in books, newspapers, magazines, packaging, and advertising.

[0003] However, water-based ink has a higher water content than oil, and the ink only needs to be baked to dry the surface; while water-based printing must be completely dry to avoid the subsequent printed content from being dissolved, so an oven for a water-based ink printer is proposed to dry the water-based ink-printed products; in addition, most existing oven air inlet ducts are only equipped with one nozzle, and this structure results in uneven air output from the nozzle, which has a poor drying effect on water-based ink-printed products. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an oven for a water-based ink printing machine in order to evenly dry the products printed by the water-based ink in view of the above-mentioned deficiencies in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an oven for a water-based ink printing machine, comprising an oven body, the oven body comprising a first shell and a second shell hinged to the first shell, characterized in that at least two groups of hot air boxes are arranged in the first shell, a first air supply duct communicating with the hot air boxes is arranged on the outer side of the group of hot air boxes, and a second air supply duct communicating with the other group of hot air boxes is arranged below the first air supply duct, a plurality of first air exhaust ports are arranged at intervals on the upper end surface of the hot air boxes, a blowing assembly is connected to the first air exhaust port in the first shell, and the first air exhaust port is communicated with the blowing assembly.

[0006] Adopting the above-mentioned technical solution: Compared with the prior art in which only one air supply duct is provided, the utility model is connected to different hot air boxes through the first and second air supply ducts respectively, and is connected to the blowing assembly through the first exhaust port provided on each hot air box, so that air can be quickly supplied to the blowing assembly and blown out evenly through the blowing assembly, avoiding the situation where the air volume at one end of the blowing assembly close to the air supply duct is greater than that at the end far away from the air supply duct, thereby causing uneven air output.

[0007] The utility model is further configured as follows: the blowing assembly includes a nozzle, an upper end surface of the nozzle is provided with an air outlet, a lower end surface of the nozzle is provided with a second air outlet corresponding to the first air outlet, and a heating tube is provided in the nozzle.

[0008] The above technical solution is adopted: by setting up a heating tube, the air transmitted to the air nozzle by the first and second air supply ducts is heated to improve the drying efficiency. At the same time, by setting up the first exhaust port and the second exhaust port, the air is transmitted and blown out from the air outlet after heating to complete the drying of the ink-printed products.

[0009] A further configuration of the present invention is that: both ends of the heating tube are provided with connectors mounted on the first shell, and both ends of the air nozzle are provided with through holes for the connectors to pass through.

[0010] The above technical solution is adopted: the blowing assembly is installed in the first shell through the setting of the connecting piece, and the through hole is provided to facilitate assembly by the staff.

[0011] A further configuration of the present invention is that the air nozzle is triangular in shape, and the air outlet is arranged at the top corner.

[0012] The above technical solution, with the triangular nozzle shape and the outlet located at the top corner, helps to blow hot air more concentratedly, so that the hot air can act more directly and evenly on the ink-printed products to be dried. This concentrated and even distribution of hot air can improve drying efficiency and shorten drying time.

[0013] A further configuration of the present invention is that a feed port is provided at one end of the second shell in the feeding direction and a discharge port is provided at the other end. At least two sets of guide rollers are rotatably provided in the second shell, and the guide rollers are located above the blowing assembly.

[0014] The above technical solution is adopted: through the setting of the feed port, the discharge port and the guide roller, it is convenient to guide and transfer the ink-printed products to be dried. During use, the ink-printed products to be dried enter the oven from the feed port and are transferred through the guide roller. One end of the guide roller can be driven by connecting to a motor. After drying is completed, the ink-printed products come out from the discharge port.

[0015] A further configuration of the present invention is that the first shell is provided with an air inlet communicating with the first air supply duct and the second air supply duct on one side thereof, and the first shell is provided with an air outlet on the same side of the air inlet, and the air outlet is communicated with the interior of the first shell.

[0016] The above technical solution is adopted: the first and second air supply ducts are connected to the external fan equipment through the air inlet to realize air supply. Through the setting of the air outlet, an effective hot air circulation system can be formed, and the dried water vapor can be taken away at the same time.

[0017] A further configuration of the present invention is that at least one hinge is provided between the first shell and the second shell on the same side, one end of the hinge is connected to the first shell, and the other end is connected to the upper shell.

[0018] The above technical solution is adopted: by setting the hinge, it is convenient for staff to open the first shell and the second shell to maintain the internal structure.

[0019] A further configuration of the present invention is that a lamp tube is provided between each of the blowing components, and a lampshade is provided above the lamp tube.

[0020] By adopting the above technical solution, the heating efficiency in the oven is improved by the arrangement of the lamp tube, and the protection of the lamp tube is improved by the arrangement of the lampshade.
